Data are presented as n or n (%). cACT: Childhood Asthma Control Test; ACT: Asthma Control Test; IOS: impulse oscillometry system. #: cACT for children aged 4–11 years [18], whereas ACT for children aged ≥12 years [19]; for both tests, a score of <20 indicates poor control (the missing values refer to children aged <4 years); ¶: resistance at 5 Hz measured on the MasterScreen impulse oscillometry system (IOS) and reported using IOS-specific normative values for children aged 3–18 years [9].
